Khun Ohm's listing is absolutely incredible if you want to experience the best of Silom (in the day and at night). Being directly opposite a 711 (you can walk there within 50 seconds from your door), it's got the best BKK has to offer in convenience. A reasonable walk away to Saladaeng and Chongnonsi BTS, with the most local of neighbourhoods and local foods, you'd be want to find more in this listing.
It's not a hotel, it's not a new renovation or place by any means, but that's fine. Khun Ohm keeps the place well and it's homely enough for your short stay in BKK (or longer, it's great too). Some more furniture or space would be fine, it was great for 1 person but 2 -3 is probably maximum. Smart TV was great for entertainment while I was WFH, loved mirroring my phone/laptop to the smart TV. Gym is reasonable and never got the chance to try the pool, but will try next time.
I've been around BKK >10 times and this listing is probably among top 5, especially for the value.
